Since moving to another house, I noticed that the voltage in this area is higher than in my old place, which was always almost exactly 120 volts. But here it goes from a low of 122.5 to as high as 125 volts depending on the time of day. Just wondering how much of an impact this has on audio gear (and everything else that plugs in) rated at 120 volts.
The power companies are allowed +/- 5%. So at 125 volts, they have 1.1 volts to go before being out of tolerance.
I would keep an eye on it, as there may be a voltage regulator failing in the neighborhood.
I had my three theater UPS units indicating that they were shaving the voltage a few years ago. When I checked the voltage in the house it was 135 volts. I got hold of the power company. Sods law operated, as it was a holiday. After talking to multiple people trying to convince them I was not an idiot, they came out. It turned out there was failing voltage regulator by the roadside about a mile away. They did thank me profusely, as they said it cold have caused a major incident. They had to order the part, which took about a week or more. However they managed to set the voltage low, which dropped quite low at peak times while waiting for the part.
However my voltage regulation allowed my equipment to get the correct voltage.
Your equipment should tolerate a +/- 5% variation in voltage though. I will say your voltage has a higher variance than I usually measure, so keep a good weather eye, so to speak.
